3 claims. (c1. 212-65) This invention relates to devices which are attached toy trucks or other cargo-carrying vehicles for the purpose of providing means fory loading or unloading articles carriedtl'iereby.v

Anvimportant object ofl thev invention. is tov providea. device of this character which can. be, attached to the vehicle itself, canbe. dismantled andI carried Within a comparatively. small. space dur-k ing.; operationv ot the vehicle, and, which` can be assembled for loading or unloadingI operationsl in, a short period. of time.`

Another important object of the` invention isto provide a device of' this character whichv can. be mounted in various positionsA of adjustment'and which embodies means for extensionA of various. of itscomponent parts,iso.as to provide for greatly. increased versatility in cargo-loading or unloading.

It.is a further object of the invention to providev a device of they character described which willI fuliill all. purposes for which it is interld'ed and will yet be'capable of being constructedcomparatively inexpensively; of handling heavy, loads, and oi possessing unusualV qualities of4 durability.

With the foregoing and other objects in view which will appear as the description proceeds, the invention' consists of certain novel-details of'con-` struction and combinationsV ofy parts, hereinafter` :more fully described and pointed out in the claims, it being understoodthat changes may be made in the construction and arrangement of parts without departing-from the spirit of the invention as claimed.

Referring to the drawing Referring to the drawing in; detail',v the vehicleto which the. invention is7 attached is indicated by the character reference 5. In the drawing andI in. this description, thisvehicle is shown as a. truck., Abut-it is understood that the invention willfhaivev application as well to vother Lcargo-carrying vehicles, 4

Thereis fixedly mounted on the. truck, by suitable means, a,k cylindrical. hollow base 6 which is.V preferably formedA of alengthof pipe material, within which thereisvertically and removably. mounted, for revolvable movement in the base 6, al cylindrical supporting member 1,v which is alsopreierably formed of pipematerial.

The-.upperv end of the supporting.` member I is exteriorly threaded, andthere is detachably mounted. on the upperend a supporting member 8, which is. approximately in the shape of af. Y., having transversely aligned openings orr bearings intits ends of. its arms and a cylindrical. hollow basewhich has interior threads-cooperatingwith Figure 1 is a side elevational;VieW-of-the'truckattachment constructed in accordance with the invention, with parts broken-- away.

The supporting member 8 is adapted. tosup- Dort. within` its sleeve 9v, the frontend oian extension arml I-'-,I- which will be described Ihereinafterin detail, therear. end of; the extension arm; III being-supportedby-a cylindrical vertical leg.,1nember I-2, which is a-composite-member preferably formedoflengths of pipe material;

Saidleg member I:-2- is vertically.- and -pivotally mounted on a dolly I3 which has a U-shaped bracket' Ill mounted; on: its platform carrying transvers ely.-aligned bearingopenings inI its arms:

ThgeglowerA endfof-j the legmember I2 is tapered i and also hasabearing opening, and is adapted to bepositioned between the arms of thebracket I4 Where iti4 is pivotally mountedby means of.. a belt;,entendingthreugn thelbracket openingsA and the1,1egnfiemberopening.` Inaddition, washers. I5

. areypositioned between-.the legsmember I2; and

the arms. of theybracketsf-'I4f.I .i

The leg` member' lf22 is ycompositelyA form-edwin telescopingf portions; the lowerfportion having spaced; vertically aligned .s openings I 61 infitsrside for receiving the ends of an adjusting pmrI] which is positioned through a registering opening in the upper portion, thereby permitting the leg member to be fixed in various positions of longitudinal adjustment. The adjusting pin I1 is horizontally positioned through an opening in the end of a, housing I8 attached to the sides of the upper portion of the leg member I2, the pin having a handle disposed exteriorly of the housing to facilitate manual operation, and being connected interiorly to the housing by a coil spring I9 having one end secured to the end of the housing and having its other end secured to the pin.

Thereyis detachably. mountedon the upper ends of the leg.member I2 lan elbow tting 29, there being cooperating threads on the leg member and Within the arm of the tting for this purpose.

There is also an extension arm II, as hereinbefore mentioned, which is of cylindrical form and is preferably formed of a length of pipe material, said arm having one end detachably mounted within the other arm of the elbow fitting Y '.Ihe extension arm I I is horizontally extended from the elbow tting 29 and has its other end horizontallyand slidably mounted in the sleeve 9. Said extension arm II is adapted to serve as a track for a rollable grooved wheel 2I. There is also provided a U-shaped suspending member 22 which has transversely aligned bearing openings disposed in the ends of its arms, and said suspending member 22 is pivotally suspended from the'wheel 2I by means of a bolt 23 which extends through the openings in the arms of the suspending member 22 and through the wheel 2| and issecured by means of nuts. Pulley means 24 depend from the suspending member 22, providing means for lifting articles into or out of the truck 5, it being understood that other lifting means; rather than a pulley attachment, can also be used if desired. In operating the truck attachment herein described, it will be seen that it is capable of being almost completely dismantled in order to be transported on the truck 5 to the point at whichV it is to be used. Ii desired, the supporting member 'I may be removed from the base 6, the sleeve supporting member 8 may be detached from the supporting'member 1, the extension arm II` removed from the sleeve, the elbow member detached from the arm II and leg member I2, the leg member I2 telescoped to reduce its length to a minimum and the dolly I3 detached from the leg member I2.

In use, the attachment can be placed in a large number of positions of adjustment, as necessary to accomplish the particular loading or unloading tasks involved. The extension armv I I can be positioned at any angle to a line drawn longitudinally through the truck 5, permitting loading or unloading from the side of the truckor the rear as necessary.

Further, the dolly I3 can be positioned on a level higher or lower than that on which the Further, it is possible to extend the length of the extension arm II, not only by reason of its slidable mounting in the sleeve 9 but also by detaching it from the elbow fitting 20 and threading an extra length of pipe material onto its length, and into the elbow fitting. Similar means can be employed to extend the length of the supporting members 'I and l2 if desired.
